I've noticed quite a few repeated questions lately. Each time it is by the same person and the questions are right after each other. I presume this is a result of multiple clicks on the submit button when posting (much like the repeat answers that were submitted to Marlboro questions the other week). Can this be stopped by changes to the coding? It would certainly remove some of the repeat questions and stop a future repeat of recent events.
I think that some of these may be a result of there being no "Preview your post" facility (I have done it accidentally myself).
The possibility of previewing and correcting a post has been asked for by several users: hopefully, it is one of the changes which we will see in the future.
